"This invention relates to'apparatus by which reinforcing -means may besupplied to a ma- "chine-by "which they are to be attached. Especially,the 'invention is concerned with the deliv- 'er-y to heel-attachingmachines of the plates v vention-is tosupply such reinforcements ofvary- :ingsizesaccurately, as to theirpositions with :respect to theheel-portion to which they are lto be'nailedandin a manner which willmini- :mize effort onthepart of the operator.

To-attainthis'object, I combine with a heelh'older, as thecustomary'heel-ringmovable into and out of .co-operation with nailingmechanism, means-for supplying reinforcements tosaidholder,-'through=which reinforcements nails are drivenrby ;thenailing mechanism into heels con- :tained in the :holder. Thereinforcement may lthus lbe positioned in the holder when this is.s'eparated from the'nailing-mechanism, and said .holder .is thenreturned to receive a heel for attachment simultaneously with thereinforce- :ment. Preferably, the reinforcements are contained-sin one-or more magazines from which .they are ejected successively intothe'holder. To reduce the burden upon the operator, thedellveryrofithereinforcements is made dependent .uponsan'other act'whichhe must perform, as the transfer of nails to the nailing mechanism.There .isrhereinzdisclosed amovable heel-ring and aniejectonmovableiinto a magazine-tube, there being connections to amechanism, as that for loading snails into the'die-block of theheel-attaching-machine, for :controlling the movementofebothsthe'iheel-ring and'the ejector. Themovemento'f the ejector isbestefiected by a spring, -Which=is=..tensioned as the ring is carriedinto its receiving position, and then permitted to act under tna-controlof a cam actuated from the loadingxmechanism. To enable the operator to.chooseiconvenientlyany one of a number of sizes .of-reinforcementsfor-attachment, as the work in lhand :may :demand, a plurality ofmagazines may bezprovided, whichzmay be brought selectively. into 1deliveringrelation to the heel-holder. In the illustrated embodiment ofthe invention,

these magazines :are :mounted upon a rotatable turret. :A chosen:magazine-may be located in "its deliveringposition'with respect to theholder, by means whi'ch'it carries and which may consisto'f arollsupporting it as theturret rotates and which, b-ymovement'of themagazine upon the'turret, enters a depression in the surface uponwhichittravels toproduce the locating effect. "Means, movable by'theoperaton'maybe utilized 'to"free"the'turret from the locating means, :asby the'elevation of a magazine to remove its roll fromthe-depression. Bymeans variable in positi'onin each'magazine, thismay be adapted for'holding reinforcements of different sizes. 'This meansis herein shownas a'postrising through the magazine and a sidewall, both the post andwall being adjustable. 'To guard against the ejected reinforcement beingthrown beyond the opening-intheholderwhich it is to enter, meansin'the'formofa'wall is provide-d'which'will de- "flect the"reinforcement into the *holder. This wall is 'preferablya'djustable tocause it to act efi-ectivelyup0n the various sizes of reinforcements. g1

One of *the many forms which my invention 'may'assume is illustrated inthe accompanying drawings, in which:

Fig. 1 is a broken front elevation of the apparatus'mounted upon aheel-attaching machine;

:Fig. 2, a top plan. view of the apparatus and more closelyassoci'atedportions of the heeling machine; and

"At 1 ll'appears'a'portion of "the'frame of aheeling machine, such, forexample, as is disclosed in Letters Patent of the United States No."1j157,688,"Glidden, October 26, 1915, this being adapted for theattachment of' a heel to asho'e 'bytheinsertion of nails through thetread-end of-said heeland-the heel-+seat of the'shoe,-Whe're theyare-clinched upon "the insole. 'The shoe is presented-upon a ack 12 tobe pressed against 'aheel supported-overa die-block [4. Through passagesin this die nail-drivers I6 "reciprocate. The *present invention ispreferably "combined with aheel-hol'der, such as that of Letters Patentof'the'United-States No. 1,365,802, Standish, January 18, 1921,=which'has a ring or plate [8 mounted in a 'frame 20 and with an ppening'z z 'formed to receive a'heel, and, in the present instance, -areinforcing plate, with its treadsurface down and positioned overthe'die block for nailing. The reinforcing plates are shown at P-in Fig.2, eachwbeing of metal of generally horseshoe-shape and-provided withopenings'p, through which the attaching :nails are to be the die, torespectively receive nails in its block 29 and deliver them for theattachment of the heel-portions. Interchangeable rings I8 are provided,one for each of the various sizes of reinforcements. These rings are soarranged in the frame 26 that the rear extremities of all sizes of thereinforcements and their rear openings are respectively at the samepoints in their receiving and nailing positions.

Considering the features peculiar to the present invention andespecially the means for supplying reinforcing plates to the ring I8,there is secured to the left of the machine-frame III, at about thelevel of the die-block I4, a bracket 30. Rising from the bracket is avertical spindle 32,

surrounded at the bottom by a bearing or spacing'ring 34. Upon this ringrests the rotatable spider36 of a turret T. At the periphery of thisspider is a series of vertical ways 38, shown as six' in number, equallyspaced from one another circumferentially (Fig. 2) and each divided intotwo vertically separated sections (Fig. 1). These ways receivecorrespondingly separated projections 40 from a bar 4I, to which isattached at 42 the inner side of a vertically extending magazine-tube44, the horizontal .con-

tour of which may approximate that of the peripheries of thereinforcements which they are to contain. Each tube is partially closedat the bottom by a plate 46, upon'which rests a stack of thereinforcements, upwardly extending lugs 48, at the ends of each of thespaced arms, being secured to the tube and having a crossbar 50connecting them. At the front of the plate 46 is an opening throughwhich the bottom reinforcement of the stackmay fall when it is pushedforward. I

It is preferable to arrange each magazine-tube to hold a plurality ofsizes of reinforcements. To permit this, and considering one only of thetubes, there rises from the bottom a post or cating member L. This maybe formed of a strip of sheet-metal, having at its lower-extremityparallel arms 52 and 54, respectively below and above the bar 50. Fromthe lower arm, an upright56 extends substantially to the top of the tubein a direction parallel to the rear curved wall. The member is then bentdownwardly and outwardly at 58, terminating in the arm 54. This arm isslotted longitudinally and through the slot passesa' screw 60 threadedinto the arm 52. The screw clamps'the post to the bar, allowing theformer to be adjusted so the upright 56, for engagement with theinsideof the stack of reinforcements P, will hold said reinforcements withtheir opposite or outer edges in close proximity to the wall of thetube. This places these edges all in the same vertical line, and themounting of the tubes upon theirprojections 40 is such, that the rearwalls of all the tubes are at the same distance from the radii of thespider which pass through the centers of the projections. This preparesfor the ejection of the reinforcements from all the magazines intoopening 22 of the plate IB for anysize of reinforcement, when this isinreceiving position, by a delivery member movable through an unvaryingdistance. To locate symmetrically reinforcements varying in widthlaterally of the tubes, there is in the lower portion of each of saidtubes and at each side thereof, an adjustable inner wall 62 ofsheetmetal. This may occupy positions close to the tube-Wall for thewider reinforcements; or may be'caused to converge inwardlyand-downwardly to centralize narrow reinforcements. At their tops, thewalls 62 are secured pivotally by screws 64 passing through theirout-turned flanges 66 and flanges 66 of the'tubes. At the bottom, thewall-flanges are widened and provided with arcuate slots I0, throughwhich are screws 12 threaded into the tube-flanges. The walls may,therefore, be bent in and out and secured by the screws 12. The effectof the positioning means upon the reinforcements will be understood uponthe comparison of the different magazine-tubes in Fig. 2.

Any one of the tubes 44 maybe brought selectively into deliveringposition by rotation of the turret T by the operator. That tube at theextreme right of the turret in Fig. 2 is so situated.

In the rotation of the turret, each tube is supported as it travels by aroll 16, rotatable about a horizontal axis at the bottom of thecorresponding bar 4i and bearing upon a horizontal surface I8 of thebracket 30., When the magazine-tube which the operator has chosenreaches the delivering position, the roll and the adjacent end of itsbar enter a depression 80 formed in the surface 78, the projections 40slidingin the ways 38. The turret is thereby held-against rotation. Tofurther and more exactly locate the selected tube by means carrieddirectly upon it, its plate 455 has depending from it a projection 82,which, as the tube falls, is received by an opening 84 in the horizontalsurface of the bracket 30. To free the positioned tube, so that theturret may be turned to present another for delivery, there is arrangedto reciprocate vertically in the bracket a slide 86, having an arm786extending-beneath theroll. Pivoted below the bracket is a hand.- lever80, the inner end of which engages the lower extremity of the slide.Upon actuation of the lever, the slide, roll, bar and tube are raised,with said roll above the surface 18. Thereupon, the operator may turnthe turret to its new position, the roll travelling from the uppersurface of the arm 83 on to and over the bracket-surface. In thiselevation of the tube, it is brought to such a level that the lowerportion Will travel clear of the ways 94 of a reinforcement-deliveringslide 96, arranged to reciprocate horizontally'upon the bracket 30.

When the nail-delivering movement of the loader-arm 28 effects theadvance of the heel-ring I6 to its reinforcement-receiving position, italso causes the slide .96 to eject a reinforcement P from themagazine-tube which is in delivering position. In this feeding action,the forward extremity of the slide enters-openings 98, 08 in thevertical wall of the tube just above the bottomplate 46, there being adivision at I00 in the slide to permit it to pass the post L. A linkI02, adjustably connected to .the slide '96 in a slot I04, is joined toan arm I06 pivoted at I08 uponthe bracket 30. A torsion-spring I I0,surrounding the arm-pivot, urges a roll IIZ rotatable upon the armagainst a cam-surface, I I4 upon a lever H6, fulcrumed at I I8 adjacentto the pivot I08. .A link I26 unites the cam-lever to the loader-arm. Assaid loader-arm, carries in the openings of its block 29 a load of nailstothe die I4, the link 26 turned clockwise (Fig. 2) :until the load isdeposited $111 .the die-block-passages. 'movement of the arm, the link26 carries the .heel-ringla from above the die-block to beneath.the'positioned magazine-tube and there temporrarily holds it. As thelink 26 acts, the link I20 'advances the: frame .20 of .the ring '18.aso that, "whentheiload of .nailsis deposited in the die- ;passages,thering-opening22 is beneath theselectedmagazine-tube. During the travelof the ring, a portion a of :thecam-surface H4, concentric- -with theaxis of its fulcrum H8, is moving alongtheroll-l I 2, so the arm I06 andthe slide -f96:rema'n'stati0nary. But when the ringis ready for'ithereception of its reinforcement, the roll isifreed by-a portion of thecam-surface at b having an abruptly decreasing radius. The spring 1| lilz'now acts to urgethe slide through the openings- 98. intothe.magazine-tube, where it engages theireinforcement at the bottom of thestack and :forcesthis forward beneath the'arm 52 of the post L todescend through the opening in the .plate dfi into the: opening 22 ofthe ring. To presvent=the ejecting force from throwing-the reinforcementbeyond the ring-opening, a stop or deflecting member is located in thepath of said reinforcement above the forward edge of the opening.IItmayconsist of a wall I22-(Fig. 3), :inclineddownwardly and outwardlybeneath the arm' 52 of the'post-L, and then bent outwardly, upwardly andinwarolly where it is adjustab ly secured by *sloteand-screw connectionsI24 (Fig. .2) tothe bar of the'magazine-tube. Its position, towardand-from the delivery-opening from the tube at the front of the plate46, may be varied to cause it to act most effectively for reinforcementsof different dimensions and weights. Upon entering the ring-opening 22,the reinforcement rests upon ahorizontal plate I26, which is secured tothe die-block-support 25. The upper surface of thisplate is flush withthe upper face of the die-block. When the loader-arm is swung back toreceive the succeeding load of nailsin the block 29, the ring l8 will berestored to its normal relation over the die-block. In its travel, thereinforcement contained in the ring-opening slides In using my improvedsupplying apparatus, thev operator places in the frame 20 a ring vl8having an opening 22, of such contour-that there will fit within itslower portion the reinforcement P to be attached, while in the upperportion will fit a heel orheel-lift to, which the attachment is to bemade. The two heel elements will be in a'definite transverse relation toeach other, so if the upper is a rubber lift in which are washers, theopenings of said washers will register with the openings 10 of thereinforcement. The magazine-tubes 44 of the turret T may contain all thesizes of reinforcements which the operator will be called upon to useduring his days work. Each tube will have its post L and walls 62adjusted to hold the stack in proper position. The nailing design of thedie-block l4 and of the loader-block 29 will, of course, alsocorrespond'to that of the openings p. If the desired size ofreinforcement is not contained in the magazine which is located indelivering position by its roll 16 and projection 82, the operator willdepress the lever to free the magazine and will then rotate the turret,the rolls of all the magazines travelling over the bracket-surface 18.The slide-arm 88, which effects the-release of the magazine, will bekept raised until-the-one chosenarrives in position,

whereupon it is released andthe roll and projection of such magazinewill descend and lock it positively'in the correct relation. The arm 28,.withaloadof 'nails'inits block 29, may now be magazine-openings fii.bottom reinforcement P in the stack advances openingi22'upon the plate i25. the-reinforcement to be thrown beyond the opening 22-is prevented byits engagement with the =Wa11' i -22, which deflects it downwardly intothe *rnent'to the shoe. tinue until another size of reinforcement isrequired-when the turret is shifted, as already de- During thisisoscillatingthe lever l [6, so its concentric camsurface a moves alongthe roll H2, holding the ejecting slide 96 against movement by its ten---sioned-spring I it). But when the surface b of the cam'reaches theroll, as the ring I8 attains its receiving r-relation, the roll isreleased and the springacts to advance the slide quickly into the Theslide, striking the this from the plate 46, so it falls through theopening in said plate and is deposited in the ring- Any tendency ofring. If, during the ejection, the reinforcement resists movement, asbecause of projecting burrs, the spring-actuated slide will stop withoutinjury to the parts. Upon restoration of the loader-arm 228: to itsnormal position, the cam-surface b withdraws the slide 96 from themagazine and retensions the spring H8. The ring H8 containing the*reinforcement returns over the die it, said reinforcement sliding'firstupon the plate I 26 and then upon theupper face of the die. With theloadereblock back in its nail-receiving position at the-foot-plate ofthe distributor, the openings p of the reinforcement are in registrationwith the die block-passages. The operator, thereupon, applies to thering-opening 22 a heel or heelportion H with its tread-end resting uponthe reinforcement, lowers the jack I 2 upon which a shoe-has been placeduntil the heel-seat of said shoe is upon the heel and starts thepower-oper- 'ation of theattaching machine.
